CHO-HP can insert into the phospholipid bilayer of liposomes, interacting with phospholipid molecules to modulate the fluidity of the liposome membrane. Its effect varies with temperature changes;
As CHO-HP is amphiphilic, possessing both hydrophilic and hydrophobic properties, it can enhance the stability of liposomes by regulating the liposome membrane.
Cholesterol, also known as cholestane, is a cyclopentane polyhydrophenanthrene derivative.
At temperatures above the phase transition temperature, CHO reduces the mobility of phospholipid fatty acid chains, thereby decreasing the fluidity of phospholipid molecules.
Conversely, at temperatures below the phase transition temperature, it prevents the interaction between phospholipid fatty acid chains, thereby preventing a significant decrease in the fluidity.
